SOLE-LEVELING MIACHINTE.

SPECIFICATION forming part of Letters Patent No. 644,654, dated March e,1900. Application filed June 15, 1899. SerialITo. 720,694. (No model.)

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the UnitedStates,residing atLynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inSole-Leveling Machines; and I do hereby declare the following to be afull, clear, and exact'description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The presentinvention relates to sole leveling or beating-out machines ofthe type disclosed in Letters Patent of the United States No. 555,548,of March 3, 1 896. In the machine of said patent there are embodied ashoe-supporting jack and a sole-leveling roll actuated byautomatically-operating connected mechanism, whereby the relativelongitudinal position and lateral inclination of the roll and jack arecaused to change during the operation of leveling the sole and all theparts of the shoe-sole brought under the action of the roll and properlyleveled and conformed to the contour of the bottom of the last.

The roller type of machine has been found generally satisfactory in use;but in some classes of work it is deemed desirable to subject the soleto a hammering or beating-out action; and it is therefore the object ofthe present invention to produce a machine of the type mentioned whichshall embody a sole-leveling hammer arranged to deliver rapid sharpblows to the sole, to level the same and conform it to the contour ofthe bottom of the last, and to so actuate the jack and hammer that theblows delivered by the ham mer shall be at all times substantiallyperpendicular to the part of the irregular surface of the sole at whichit shall at any given time be operating.

To the above end the present invention consists of the devices andcombinations of devices, which will be hereinafter described andclaimed.

In the accompanying drawings I have illustrated the present invention asbeing embodied in the machine described in the patent hereinbeforementioned, in which are disclosed two separate sole-leveling mechanismsactuated by connected mechanism to properly actuate one jack and itscooperating sole-lew eling instrumentalities to level a left shoe andthe other to level a right shoe, and such is the preferred form of thepresent invention; but it is in no way limited to such a construction.

In the drawings, Figure 1 shows in side elevation a sole-levelingmachine embodying the present invention, a portion of the frame beingbroken out to show underlying parts.

Fig. 2 shows a top plan View with the jacks and their operatingmechanism removed.

' Fig. 3 shows a front view of one of the soleleveling hammers and partsof its actuating mechanism. Fig. 4 shows a section on line a: as, Fig.3. Fig. 5 shows a broken side elevation of the rear end of the hammersupporting a frame and parts of the hammer-actuating mechanism. Fig. 6shows a plan view of the same mechanism. Fig. 7 shows a section on liney y, Fig. 6.

Similar reference characters will be employed throughout thespecification and drawings to designate corresponding parts.

In the drawings, 1 represents the main frame, of suitable size and shapeto support the working parts and substantially the same as the frame inthe patent hereinbefore referred to. The jacks 2 may be of any usual orpreferred construction, and,as in the patented machine, they arefulcrumed upon a shaft 3, mounted in suitable bearings in the frame 1.Each jack is oscillated about its fulcrum by means of a lever 4, whichis fulcrumed on a shaft 5 and pivotally connected to a link 6, which inturn is pivotally connected to an arm 7, extending from the shaft 3, thelever 4 carrying a cam-roll (not shown) which engages a cam-path 8 onthe side of the disk or Wheel 9. The disk or wheel 9 is mounted upon ashaft 10, having suitable bearings in the frame 1, and is rotated bymeans of a worm 11, carried by a shaft 12, mounted in bearings in theframe 1, which worm engages a worm-gear (not shown) on the disk orwheel. The shaft 12 is driven from the power-shaft 13 by means of a gearlet, mounted on said shaft, engaginga gear 15 on the power-shaft, thepower-shaft carrying suitable pulleys l6, driven by a belt from anysuitable source of power.

The foregoing arrangement is substantially the same as in the patenthereinbefore referred to, and in operation the rotation of the disk orwheel 9 will impart to the jacks 2 escillating movements to carry thesole of the shoe which may be on the jack longitudinally beneath thesole hammering mechanism, which will be hereinafter described.

Cooperating with each jack is a sole-leveling hammer, which is rapidlyreciprocated toward and from the sole of the shoe to subject the sole toshort, sharp, and quick blows as the shoe and jack pass beneath thesame, and as it is necessary that the blows of the hammer be deliveredon the sole in a line substantially perpendicular to the surface of thesole at all points of the irregular contour of the sole I have providedmeans for automatically adjusting the relative lateral and longitudinalinclination of the jack and hammer, and in the machine of the drawingsthis relative adjustment is secured by mounting the hammer in a carrierwhich is capable of being tipped both longitudinally and laterally abouta point substantially at the face of the hammer.

Each hammer 16 is secured toa cross-head 17, mounted to reciprocate inguides 18, formed in vertical uprights 19, carried by the oscillatinghead 20. The cross-head 17 is connected to a block 21 (which alsoreciprocates in the guide 18) by means of a bolt 22, which passesloosely through bearings 23 in the block 21 and cross-head 17, and saidbolt is surrounded by a coiled spring S, interposed between the crosshead 17 and block 21, whereby the blows of the hammer are cushioned.

Any suitable means may be provided for actuating the hammer, that shownin the drawings comprising a shaft 24, mounted in suitable bearings 25,carried by the vertical uprights 19, which shaft carries eccentrics 251,engaged by eccentric-straps 26, carried by links 27, pivotally connectedto the block 21. Upon one end of the shaft 24 is a pulley 27 over whichpasses a belt or cord 28, which is driven from a pulley 29, mounted toturn on a shaft 30, secured in suitable bearings at the side of the head20. The pulley 29 is formed integrally with or connected with anotherpulley 301, which is driven by a belt or cord 31, which passes aroundidle pulleys 32, mounted on a vertical shaft 33 at the side of theoscillating head 20, thence under and through an opening 34 in saidhead,and around a pulley 35, mounted on a stud 36 in the head 20. (Seedotted lines, Fig. 2.) Attached to or formed integrally with the pulley35 is a pulley 361, which is driven by a belt or cord 37, which passesout of the opening 34 and beneath the head 20 and thence around idlepulleys 38, carried by a vertical shaft 30, secured in a bearing carriedby an arm 40, projected from the frame 41, and thence over a pulley 42,mounted on a stud 43, which pulley is formed integrally with orconnected to a belt-pulley 44, driven by a belt 441 from the pulley 45on the shaft 13.

The above arrangement is such that a rotation of shaft 13 will rotatepulley 45 and by means of the belt 441 rotate pulleys 44 and 42, whichin turn, through the belt or cord 37 and pulleys 361 and 35 and belt orcord 31 and pulleys 301 and 29 and belt or cord 28 and pulley 27 rotatethe shaft 24, which by means of the eccentrics 25 and straps 26 impartsrapid reciprocations to the hammer 16, which as the jack and shoethereon are oscillated, as hereinbefore described, will deliver short,sharp, and quick blows to the sole of the shoe. The bottom of theshoe-sole is of an irregular curved contour, it being curved slightly atthe shank and fore part transversely or laterally from side to side ofthe shoe and from toe to heel. The line is in the nature of a compoundcurve, it being convex at the fore part and more or less concave at theshank and some parts of the surface are higher than others, and as thework progresses over the surface of the sole the hammer must be raisedand lowered accordingly, as a high or low part of the sole is beneaththe same and tilted laterally to accommodate itself to the lateralcurvature of the sole and longitudinally to accommodate itself to thelongitudinal curvature of the sole.

In the present machine suitable mechanism has been provided toautomatically raise and lower the hammer and to tilt the same bothlaterally and longitudinally in proper time relation to the movements ofthe jack and the particular portion of the shoe-sole which at any timemay be under the hammer, the relative tilting movements of the hammerand jack being for the purpose of causing the blows of the hammer to bedelivered in a line substantially perpendicular to the surface of thesole, as hereinbefore described.

The lateral tilting of the hammer in the machine of the drawings isobtained by mounting the head 20 on a tubular shaft 46, which is mountedto turn in a tubular bearing 47 of the frame 41, which frame is pivotedat 48 in suitable bearings to the frame of the machine to permit thehammer to be raised and lowered toward and from the sole of the shoe, aswill be hereinafter described.

To the rear end of each of the tubular shafts 46 is secured an arm 49,carrying a segment 50, (see dotted lines, Fig. 1,) which engageshorizontally-reciprocating rack-bars, which are reciprocated in oppositedirections by means substantially like the machine of the patenthereinbefore referred to and which need not be herein described, itbeing understood that one head and 11am mer will be rocked laterally tolevel a left shoe and the other to level a right shoe, substantially inthe same hammer as the leveling-rolls of the patented machine areactuated.

The rise and fall of the frame 41 is accomplished in the machine of thedrawings by means of a link 51, which is pivotally connected thereto andto a block 52, which is adjustably mounted in a slotted arm 53 of abellcrank lever 54, pivoted at 55 to.thc frame 1 and having an arm 56engaging the periphery of a cam 57, mounted on the shaft 10.

The longitudinal tilting movement of the hammeris secured in the machineof the drawings by pivotally mounting the vertical uprights 19 on thestuds 30 and 300, carried by the head 20, so that they may tip forwardand back in a longitudinal direction. This tilting of the uprights 19 isaccomplished by means of a link 58, which is pivotally connected at 59to a cross-girth 591, connecting the uprights 19 at the back, and to ahorizontally-reciprocating rod 60, movable in bearings 61, carried bythe head 20, which rod carries at its rear end suitable stop-nuts 62,between which is received a forked arm 63, carried by a rod 64, which isreciprocated in suitable bearings 65, carried by the frame 41, the rearend of said rod 64 being pivotally connected to the upper end of a lever66, passing through an aperture 67 in frame 41 and mounted on arock-shaft 6S, journaled in suitable hearings in the frame 1. An arm 66is fixedly secured to the rock-shaft 68 and connected to a link 69,which in turn is pivotally connected to a block 70, adjustable along the.slotted arm 71 of a lever 72, fulcrumed at 55 to the frame 1, the lowerarm of which carries a cam-roll 73, which engages a cam-path 74, formedin the cam 57.

It is deemed desirable that the hammer 16 be formed with twohammering-faces, such as a comparatively-flat face 75 and a rounded face76, the flat face being employed when operating on the fore part of theshoe and the rounded face being employed when operating upon the shankof the shoe, and in the machine of the drawings Ihave provided means forautomatically bringing the faces of the hammer into operative positionat the proper times, according to the part of the shoe-sole which may beunder the hammer at anyparticular time. To accomplish this result, thehammer 16 is fixedly secured to a shaft 77, which is mounted to rock inbearings 78 in the cross-head 17, one end of said shaft being projectedlaterally through an opening 79, formed in one of the uprights 19 andcarrying an arm 80, which is pivotally engaged bya link 81, which inturn is pivoted to a reciprocating rod 82, passing through the tubularshaft 46 and being pivotally connected at its rear end to a lever 821,which engages said rod through openings 83 and 84, formed in the tubularbearing 47 of frame 41 and. in the tubular shaft 46, the said leverbeing fixedly secured to a rock-shaft 85, which carries an arm 851,pivotally connected to a link 86, which is pivotally connected to alever 87, fulcrumed at 88 to the frame 1 and carrying a cam-roll (seedotted lines, Fig. 1) engaging a cam-path 89, formed in the cam 57.

Like the machine of the patent hereinbefore referred to, the presentmachine may be provided with suitable start-and-stop mechanism and meansfor adjusting the extent of the varihammer to cause the action of thehammer.

to be prolonged at any point in the sole desired, all of which in theillustrated machine are substantially the same as in the machine of thepatent.

In the illustrated embodiment of the present invention I haverepresented the same as being embodied in a duplex machine that is, amachine comprising a plurality of shoesupporting jacks and asole-leveling hammer codperating with each jack-and it will be necessaryin the operation of this machine one jack and its cooperating hammerwill be actuated to level a left shoe, and the other jack and itscooperating hammer will be actuated to level a right shoe, the severalcams being formed and arranged to impart to the respective jacks andhammers their relative movements timed and arranged to produce thedesired operation of the hammers at any particular point in theshoe-sole which may be at any time under the hammer. It is to beunderstood, however, that the present invention is not in any senselimited to its em bodiment in a duplex machine nor to the details ofconstruction and arrangement which have been particularly illustratedand described.

The operation of the machine itself has been sufficiently described inconnection with the foregoing description of its construction andarrangement, and a further description thereof is deemed unnecessary.

Having described the construction and mode of operation of my invention,I claim as new and desire to secure by Letters Patent of the UnitedStates-- 1.
